4. Buying Decision Framework

Here are three practical questions to ask yourself when deciding between these two devices:

  1. Do you need the immersive experience of a large, foldable screen or the responsiveness of a standard display?
    • If a large screen for multitasking and media is your priority, then the Fold3 is for you.
    • If you prefer smoother animations, high brightness, and a more standard form factor, then the ROG Phone 8 is the better option.
  2. Is raw performance or camera flexibility more important to you?
    • If you want the best performance in apps and gaming, and superior image quality from its primary camera, the ROG Phone 8 is the winner.
    • If you prioritize having multiple lenses, wireless charging, and an eSIM, then the Fold3 provides better flexibility.
  3. Do you need longer battery life, or wireless charging capabilities?
    • If you want an all-day battery life and very fast charging, the ROG Phone 8 is the obvious choice.
    • If you prioritize wireless charging, then the Fold 3 provides the edge.

My Choice

If I had to choose between these two devices, I'd go with the Asus ROG Phone 8. While the foldable nature of the Z Fold3 is certainly innovative and appealing, the ROG Phone 8 wins me over with its sheer power, superior display, longer battery life, faster charging, and better camera sensor. As someone who appreciates a smooth, responsive experience and enjoys gaming on mobile, the ROG Phone 8 simply provides more of what I value in a smartphone today.

The Samsung Galaxy Z Fold3 5G is still a good phone, it offers a unique form factor and better camera system, but it is a bit older, its performance lags behind today's devices, and the ROG Phone 8 wins in most other aspects. For me, the ROG Phone 8 offers the best combination of power, performance, and an incredible visual experience and a better camera at this point in time.
